FERROUS SULFATE Chemical Properties,Uses,Production


  • Nutritional supplements (iron enhancer); color former of fruit and vegetable; for example, the salted product used together with dried alum in eggplant can form stable complex salt with its pigment to prevent the discoloration caused by organic acids. However, it should be noted, for example, it will turn into black ink upon excess amount of iron. When the amount of alum is high, the meat of the pickled eggplant meat will become excessively solid. Formulation example: long eggplant 300 kg; edible salt 40kg; ferrous sulfate 100g; dried alum 500g. It can still be used as the color forming agent of black beans, sugar boiled beans and kelp. Food containing tannins, in order to avoid of causing blackening, should not be used. It can also be used for sterilization, deodorization and very weakly bactericidal.
  • Legumes contained cryptochromic pigment is colorless upon reduction state while being oxidized into black upon oxidation in alkaline condition. Taking advantage of the reduction property of ferrous sulfate can achieve the purpose of color protection with the usage amount of 0.02% to 0.03%.
  • If is used for the manufacturing of iron salt, iron oxide pigments, mordant, purifying agent, preservatives, disinfectants and medicine for anti-anemia drugs

Chemical Properties

Greenish or yellow-brown crystals or granules; odorless. Soluble in water with saline taste; insoluble in alcohol. hygroscopic.

Chemical Properties

Ferrous sulfate is a greenish or yellowish solid in fine or lumpy crystals.


Ferrous Sulfate is a nutrient and dietary supplement that is a source of iron. it is a white to grayish odorless powder. ferrous sulfate hep- tahydrate contains approximately 20% iron, while ferrous sulfate dried contains approximately 32% iron. it dissolves slowly in water and has high bioavailability. it can cause discoloration and rancidity. it is used for fortification of baking mixes. in the encapsulated form it does not react with lipids in cereal flours. it is used in infant foods, cereals, and pasta products.


Iron Supplement


Ingestion causes intestinal disorders.

Agricultural Uses

Copperas, also called green vitriol, is ferrous sulphate heptahydrate. It is an iron salt fertilizer, which is most effective in overcoming iron deficiency.

Agricultural Uses

Ferrous sulphate heptahydrate (FeSO4.7H2O), also called green vitriol or copperas, is a blue-green water-soluble crystal and is the best known ferrous salt. It is obtained by the action of dilute sulphuric acid on iron in a reducing atmosphere. The anhydrous compound is very hygroscopic. It gets oxidized gradually in an aqueous solution. On heating, the solid decomposes to give red ferric oxide, sulphur trioxide (SO3) and sulphur dioxide (SO2).

Safety Profile

A human poison by ingestion. Moderately toxic to humans by an unspecified route. An experimental poison by ingestion, intraduodenal, intraperitoneal, intravenous, and subcutaneous routes. Human systemic effects by ingestion: aggression, somnolence, brain recorlng changes, diarrhea, nausea or vomiting, bleedmg from the stomach, coma. Questionable carcinogen with experimental tumorigenic data. Experimental teratogenic and reproductive effects. Mutation data reported. Potentially explosive reaction with methyl isocyanoacetate at 25'. May igmte on contact with arsenic trioxide + sodium nitrate. When heated to decomposition it emits toxic fumes of SOx. See also IRON COMPOUNDS.

Potential Exposure

It is used as a fertilizer, food or feed additive; and in herbicides; process engraving; dyeing, and water treatment. A byproduct of various chemical and metal treating operations.

First aid

If this chemical gets into the eyes, remove any contact lenses at once and irrigate immediately for at least 15 minutes, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts the skin, remove contaminated clothing and wash immedi ately with soap and water. Seek medical attention immedi ately. If this chemical has been inhaled, remove from exposure, begin rescue breathing (using universal precau tions, including resuscitation mask) if breathing has stopped and CPR if heart action has stopped. Transfer promptly to a medical facility. When this chemical has been swallowed, get medical attention. Give large quanti ties of water and induce vomiting. Do not make an uncon scious person vomit.


Aqueous solution is acidic. Contact with alkalies form iron. Keep away from alkalies, soluble carbo nates; gold and silver salts; lead acetate; lime water, potassium iodide; potassium and sodium tartrate; sodium borate; tannin.
